i have a 2010 fit, with mugen rear underspoiler. i put on the mugen sport muffler. i didnt get the street tuner sound i wanted. is there something out there that will attach to the mugen stainless steel exhaust and will fit in the underspoiler opening?

 

Wow, really? Cuz that's a beautiful sounding muffler. What are you looking for, something louder? Just look through these forums, there are dozens of threads and links to videos of exhausts. Go find the sound you're looking for.

 

something louder. in the car its a nice deep sond but outside it sounds almost stock. i take solice though that i probably have the most expensive muffler in the county. i m not looking to replace but to find attacment to amplify, and one that will fit the underspoiler

 

Have a shop weld up a new b-pipe without the resonator. That piece is the pipe the muffler hooks onto. That will increase the noise considerably, although that exhaust is actually already kind of loud from what I've heard on youtube. Go for it. Report back.

 

B-SPEC FIT with only cat-delete exhaust...
